APPARATUS FOR MASHING.

SPECIFICATION forming part of Letters Patent No. 368,076, dated August 9, 1887.

Y Application filed February 1f), 15,87.v Serial 227,140. (No model.)

To all whom it may concern,.-

the United States, residing at New York, in the county and State of4 New York, have invented new and useful Improvements in Apparatus for Masliing, of which the following is a specification.

.This invention relates to improvements in meshing apparatus', -as set forth in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure 1 is a front elevation, partly in section, of a mashing apparatus. Fig. 2 is aseotion in the planear x, Fig. l; and Fig. 3, a detail view, partly in section, showing portions of the main shaft and stirrer-shafts.

Similarletters indicate corresponding parts. In the drawings, the letter A indicates a mash-tub. In a bearing or support, B, turns a main shaft, C; Abevel-gear, D, keyed or secured to themain shaft, is adapted to actuate the main shaft. Suitable actuating mechanism-such as a pulley, G, driving-shaft F, and bevel-gear E-are shown as adapted to aetuate the bevel-gear D. The motion of the main shaft C imparts motion tothe stirrer-shafts K. Gears H and I are shown as adapted to transmit motion from the main shaft C to the stirrer-shafts. By having the driving-gear H on the main shaft C,'located above the stir-rer shafts, as shown, .the material at the bottom of the tub A is not liable to rise to the drivinggear H. Said gear H is thus not liable to be choked by the material which is being operated on at the bottom ofthe tub A.

The driving-gear H is shown as firmly connected to the main shaft G. The connectinggears I are shown as firmly connected .to the stirrer-shafts K. By rotating the main shaft C in the direction of arrow l the stirrer-shafts K will be caused to rotate, as indicated by arrows 2 and 3.

The stirrers J are rmly connected to the stirrer-shafts K, and move with said stirrershafts. Supplementary or secondary stirrers, L, between the gears I and the main shaft C tend to clear the space between the gears I and the main shaft C from material which has a tendency to lodge in such space. The drivinggear H and connecting-gear I cause the stirrer-shafts to rotate about their `own axes. The stirrer shafts K also move Be 1t known that We, JOHN P. DOELFL and JOHN CHRISTIAN G. HPFEL, both citizens of l about the main shaft G, as will be now described. The stirrer-shafts K are supported or borne by hangers M. The hangers M are connected to arms or to a frame, N, loosely mounted on the main shaft. The arms or frame N are connected toasleeve, O. The sleeveO is mounted loosely on-the main shaft C, and said vsleeve O is adapted to rotateindependently of the main shaft C. A bevelgear, l?, connected to the sleeve O, is adapted to actuate the sleeve O. A pulley, S, shaft, R, and bevelgear Q are shown as adapted to actuate the bevclgear P and sleeve O. A suitable shoulder, Y, on the main shaft G is shown as adapted to support the sleeve O.

The rotation of the sleeveO carries the frame or arm N and the sti rrer-shafts K about the interior of the tub A. The stirrer-shafts'K are also shown as being loosely connected to the main shaft C.

The collar Z, which loosely encircles the main shaft C, supports the inner ends of the stirrer-shafts K, and said main shaft C is free to turn in the collar without the stirrer-shafts moving around in a horizontal plane in the mash-tub.

By having the sleeve O adapted to move independent-ly of the main shaft C different speeds can be imparted to the sleeve O and to the main shaft C. Such different speeds can be made to impart different speeds to the n10- tion of the stirrershafts K about their own axes and about the main shaft C, which may be of advantage to the operator. The driving-shafts F R may be actuated independently of one another, or said shafts F R may be connected by gears T U. By having the gears T U of different sizes or diameters the shafts F It, when geared together, can be ICO lt will be understood that we do not broadly elaini a horizontal slirrer-shaft supported by a hanger suspended from an arm carried by a Vertical main shaft, nor do we claim the eolnbination, with such main shaft and Stirrershaft, of dri\-'ingshal'ts provided with separate pulleys and with ad justablegears, whereby the main shaft and stirrerw shaft can be rotated either together or independently at the same or different speeds, such being shown in the application of Joh n P. Doelfel, one of the present applicants, filed January 27, 1887, Serial 1N o. 225,694. Y

What we Claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the main shaft C and stirrer-slial'ts .K K, of the gears H I I, connecting said shafts, a frame,`N,1nounted loosely on the main shaft and provided with hangers M to support the stirrer-shafts, a sleeve, O, loosel y surroulndi ug the main shaft and secured to said. frame N, and means for rotating said sleeve and main shaft in opposite directions, substantial] y as shown and described.

2. The combination, with the main shaft G and a stirrershaft, K, ol a drivinggear, H,

connecting-gear I, primary stirrers J', and a secondary stir-rer, L, situated between thegear I and the main shaft, substantial] y as setforth.

3. The combination ot' the main shaft @,stir rer-shafts K l, gears H I, frame or arms N, mounted loosely on the main shalt and provided with hangers M, the sleeve O, secured to said frame, the gear Ion said loose sleeve, the gear D on the main shaft, and means for aetnating said gears on the sleeve and main shaft, either together or independently, at varying speeds, substantially as described.

In testimony whereof we have hereunto set our hands and seals in the presence of two subseribing witnesses.
